Intel Pentium 4 670 CPU Review. Page 2

Today Intel launches the new 6xx series processors with the 3.8GHz core clock frequency. This processor has every chance to become the fastest from the working frequency point of view in the entire family of NetBurst based solutions. Let’s find out now if its frequency is high enough to make it a performance leader.

As we see, the newcomer doesn’t strike as with anything special. This CPU is a full analog of Pentium 4 660 with that only difference that it works at higher clock frequency.

The diagnostic CPU-Z utility provides the following information about this processor:

Here I would like to note that this CPU, just like all other processors based on Prescott-2M core with the clock frequency multiplier over 14x, supports Demand Based Switching technologies set, i.e. C1E (Enhanced Halt State) Technology, TM2 (Thermal Monitor 2) Technology and EIST (Enhanced Intel SpeedStep) Technology. These technologies make the CPU reduce its working frequency to 2.8GHz in case of overheating or in the idle mode, which is actually no surprise for us, I should say.
